Abstract

Recording device One kind of information Will be created by Input receiver unit To get the first and second digital data, which within the ratio of the chester size is not equal Integer ratio The semantic block is arranged to insert the first data nA and the second data mB (n and m are integers equal to 2 or greater and n / m). Shector's First Data Is set to A and the shector size of the second data is set to B and to compose the data of the block structure; The recording processing unit to perform encryption to correct errors and digital modulation with the data of the block structure; And the recording unit to save the record from The processing unit is logged. In the recording medium:

Claims (1)

1.Data recording device to record digital data into the recording medium. That consists of Import way To get digital information The first and second in which there is no ratio between sector sizes, not integer ratio. How to organize blog segments To insert the first data, nA and second data, mB (n and m are integers equal to 2 or more and n / m) into a pre-defined block size and construct the data. A lock assumes the vector size of the first such data.
